This research study investigates how genetic mutations in the Kmt2c and Kmt2d genes create a "field effect" that predisposes normal bladder tissue to cancer. By using genetically engineered mice, scientists discovered that losing these epigenetic modifiers disrupts cellular differentiation and causes a redistribution of the KMT2A–menin complex within the genome. These molecular shifts result in a pre-cancerous state where histologically healthy tissue becomes hyper-responsive to inflammatory signals and growth stimuli. The findings suggest that these early mutations effectively prime the…
